Structural Steel - Theory & Concepts

Grades, mechanical properties, and testing of structural steel.

Adjust axial strain ( $\varepsilon$ ) to compute the resulting stress ( $\sigma$ ) within the linear elastic region.

Axial Strain ($\varepsilon$)0.100%

No Strain (0.0)Elastic Limit (0.002)

Young's Modulus ($E$): Structural steel exhibits a constant modulus of elasticity of approximately

200,050\text{ MPa}

(

200\text{ GPa}

) in the elastic range.

Elastic Deformation

\sigma = E \cdot \varepsilon

\sigma = 200,000 \cdot 0.0010

\sigma = 200 \text{ MPa}

Stress is strictly proportional to strain.
